Episode description

Welcome to the very first episode of HVAC Underground. Before you condemn a compressor, dump in a pound of refrigerant, or tell a customer they need a whole new system — listen up. Most rookie callbacks don't come from hard jobs. They come from five service calls that look dead simple and aren't.

In this episode we walk through the five calls new techs blow most often: what you think is happening, what's actually happening, and how to nail the diagnosis so you're not the reason the customer calls back. No fluff, no corporate spin — just the stuff you usually only learn after years on the truck.

If you turn wrenches, read gauges, or run service calls for a living, this one's for you.

What you'll learn

• Why a "no cooling" call is usually airflow — not refrigerant
• How to test a capacitor before you condemn a compressor (and pick the right microfarad)
• What a frozen evaporator coil is really telling you — and why adding gas makes it worse
• The low-voltage checks that save you from chasing a "dead" system for an hour
• Why charging by gauge pressure alone is how you earn a callback

HVAC Underground – Episode 3

Why Great HVAC Companies Never Struggle to Hire

Every HVAC contractor is looking for technicians—but why do some companies always seem to attract the best talent while others struggle to fill open positions?

In this episode of HVAC Underground, Randy Castricone explores what separates great HVAC companies from the rest. The answer isn't just higher pay or better benefits. It's about building a culture people want to be part of.

Following up on our discussion about the HVAC labor shortage in Episode 2, we dive into the leadership, reputation, and company culture that turn businesses into employers of choice. Recruiting doesn't start when you post a job—it starts with the experience your employees have every day.

Whether you're an owner, service manager, operations leader, or technician, this episode will challenge you to rethink how you build and grow your team.

In This Episode

• Why some HVAC companies always seem to attract top talent
• The difference between hiring and recruiting
• Why company culture is your greatest recruiting tool
• The real reasons technicians leave employers
• How leadership impacts retention
• Building an employer brand that technicians trust
• Why storytelling beats traditional job postings
• Practical steps every contractor can take to become an employer of choice

Key Takeaway

Great companies don't wait until they need people to start recruiting. They invest in their employees, build strong leadership, create a positive culture, and earn a reputation that attracts talent before positions ever open.
